Leadership and governance

ISIL is headed and run by
Abu Bakr al-Baghdadi. Before their deaths, he had two deputy leaders,
Abu Muslim al-Turkmani
for Iraq and Abu Ali al-Anbari
(also known as Abu Ala al-Afri)[66]
for Syria, both ethnic Turkmen. Advising al-Baghdadi is a cabinet of senior leaders, while its operations in Iraq and Syria are controlled by local governors.[67][68]
Beneath the leaders are councils on finance, leadership, military matters, legal matters (including decisions on executions) foreign fighters' assistance, security, intelligence and media. In addition, a shura
council has the task of ensuring that all decisions made by the governors and councils comply with the group's interpretation of sharia.[69]
While al-Baghdadi has told followers to "advise me when I err" in sermons, according to observers "any threat, opposition, or even contradiction is instantly eradicated".[70]

According to Iraqis, Syrians and analysts who study the group, almost all of ISIL's leaders—including the members of its military and security committees and the majority of its
emirs
and princes—are former Iraqi officers, specifically former members of Saddam Hussein's
Ba'ath
government who lost their jobs and pensions in the de-Ba'athification
process after that regime was overthrown.[71][72][73]
The former Chief Strategist in the Office of the Coordinator for Counterterrorism of the US State Department, David Kilcullen, has said that "There undeniably would be no Isis if we had not invaded Iraq."[74]
It has been reported that Iraqis and Syrians have been given greater precedence over other nationalities within ISIL because the group needs the loyalties of the local Sunni populations in both Syria and Iraq in order to be sustainable.[75][76]
Other reports, however, have indicated that Syrians are at a disadvantage to foreign members, with some native Syrian fighters resenting "favouritism" allegedly shown towards foreigners over pay and accommodation.[77][78]

In August 2016, media reports based on briefings by Western intelligence agencies suggested that ISIL had a multilevel secret service known in Arabic as
Emni, established in 2014, that has become a combination of an internal police force and an external operations directorate complete with regional branches. The unit was believed to be under the overall command of ISIL's most senior Syrian operative, spokesman and propaganda chief
Abu Mohammad al-Adnani[79][80]
until his death by airstrike in late August 2016.[21]

Civilians in ISIL-controlled areas

In 2014
The Wall Street Journal
estimated that eight million people live in areas controlled by ISIL.[81]Al-Raqqah
in Syria has been under ISIL control since 2013 and in 2014 it became the group's de facto
capital city.[82]
The United Nations Commission on Human Rights
has stated that ISIL "seeks to subjugate civilians under its control and dominate every aspect of their lives through terror, indoctrination, and the provision of services to those who obey".[83]
Civilians, as well as the Islamic State itself, have released footage of some of the human rights abuses.[84][85]
Since December 2013, ongoing clashes have occurred throughout western Iraq
between tribal militias, Iraqi security forces, and ISIL. In early January 2014, ISIL militants successfully captured the cities of Fallujah
and Hīt,[86]
bringing much of Anbar Province
under their control. In June 2014 ISIL took over the Iraqi city of Mosul.

Estimates of the size of ISIL's military vary widely from tens of thousands[88]
up to 200,000.[32]
In early 2015, journalist Mary Anne Weaver estimated that half of ISIL fighters are foreigners.[89]
A UN report estimated a total of 15,000 fighters from over 80 countries were in ISIL's ranks in November 2014.[90]
US intelligence estimated an increase to around 20,000 foreign fighters in February 2015, including 3,400 from the Western world.[91]
In September 2015, the CIA estimated that 30,000 foreign fighters had joined ISIL.[92]

According to Abu Hajjar, a former senior leader of ISIL, foreign fighters receive food, petrol and housing, but unlike native Iraqi or Syrian fighters, they do not receive payment in wages.[93]

Non-combatants

Although ISIL attracts followers from different parts of the world by promoting the image of holy war, not all of its recruits end up in combatant roles. There have been several cases of new recruits expecting to be
mujahideen
who have returned from Syria disappointed by the everyday jobs that were assigned to them, such as drawing water or cleaning toilets, or by the ban imposed on use of mobile phones during military training sessions.[94]

ISIL publishes material directed at women. Although women are not allowed to take up arms, media groups encourage them to play supportive roles within ISIL, such as providing first aid, cooking, nursing and sewing skills, in order to become "good wives of jihad".[95]
In a document entitled Women in the Islamic State: Manifesto and Case Study
released by the media wing of ISIL's all-female Al-Khanssaa Brigade, emphasis is given to the paramount importance of marriage and motherhood (as early as nine years old). Women should live a life of "sedentariness", fulfilling her "divine duty of motherhood" at home, with a few exceptions like teachers and doctors.[96][97]
Equality for women is opposed, as is education on non-religious subjects, the "worthless worldly sciences".[97]

Non-conventional weapons

The group uses truck and
car bombs,
suicide bombers
and IEDs, and has used
chemical weapons
in Iraq and Syria. ISIL captured nuclear materials from Mosul University
in July 2014, but is unlikely to be able to convert them into weapons.[102][103]
In September 2015 a US official stated that ISIL was manufacturing and using mustard agent
in Syria and Iraq, and had an active chemical weapons research team.[104][105]
ISIL has also used water as a weapon of war. The group closed the gates of the smaller Nuaimiyah dam in Fallujah in April 2014, flooding the surrounding regions, while cutting the water supply to the Shia-dominated south. Around 12,000 families lost their homes and 200 km² of villages and fields were either flooded or dried up. The economy of the region also suffered with destruction of cropland and electricity shortages.[106]

Traditional media

In November 2006, shortly after the group's rebranding as the "Islamic State of Iraq", it established the Al-Furqan Foundation for Media Production, which produces CDs, DVDs, posters, pamphlets, and web-related propaganda products and official statements.[110]
It began to expand its media presence in 2013, with the formation of a second media wing, Al-I'tisam Media Foundation, in March[111][112]
and the Ajnad Foundation for Media Production, specialising in Nasheeds
and audio content, in August.[113]
In mid-2014, ISIL established the Al-Hayat Media Center, which targets Western audiences and produces material in English, German, Russian and French.[114][115]
When ISIL announced its expansion to other countries in November 2014 it established media departments for the new branches, and its media apparatus ensured that the new branches follow the same models it uses in Iraq and Syria.[116]
FBI Director James Comey
has described ISIL's "propaganda is unusually slick," noting that, "They are broadcasting... in something like 23 languages".[117]

In July 2014, al-Hayat began publishing a digital magazine called
Dabiq, in a number of different languages including English. According to the magazine, its name is taken from the town of
Dabiq
in northern Syria, which is mentioned in a hadith
about Armageddon.[118]
Al-Hayat also publishes a digital magazine in Turkish called Konstantiniyye, the
Ottoman
word for Istanbul,[119][120]
and another in French called Dar al-Islam.[121]
The group also runs a radio network called Al-Bayan, which airs bulletins in Arabic, Russian and English and provides coverage of its activities in Iraq, Syria and Libya.[122]

Social media

ISIL's use of
social media
has been described by one expert as "probably more sophisticated than [that of] most US companies".[107][123]
It regularly uses social media, particularly Twitter, to distribute its messages.[123][124]
The group uses the encrypted instant messaging service Telegram
to disseminate images, videos and updates.[125]

The group is known for releasing videos and photographs of beheadings, shootings, caged prisoners being burnt alive or submerged gradually until drowned.[126]
Journalist Abdel Bari Atwan
described ISIL's media content as part of a "systematically applied policy". The escalating violence of its killings "guarantees" the attention of the media and public. Following the plan
of al-Qaeda strategist Abu Bakr Naji, ISIL hopes the "savagery" will lead to a period of "vexation and exhaustion" among its Western enemies, where the US will be drawn into a direct fight with ISIL, and lacking the will to fight a sustained war will be "worn down" militarily.[70]

Along with images of brutality, ISIL presents itself as "an emotionally attractive place where people 'belong', where everyone is a 'brother' or 'sister'. The "most potent psychological pitch" of ISIL media is the promise of heavenly reward to dead jihadist fighters. Frequently posted in their media are dead jihadists' smiling faces, the ISIL 'salute' of a 'right-hand index finger pointing heavenward', and testimonies of happy widows.[70]
ISIL has also attempted to present a more "rational argument" in a series of videos hosted by the kidnapped journalist John Cantlie. In one video, various current and former US officials were quoted, such as US President
Barack Obama
and former CIA
Officer Michael Scheuer.[127]

In 2014, the
RAND Corporation
analysed ISIL's funding sources from documents captured between 2005 and 2010.[130]
It found that outside donations amounted to only 5% of the group's operating budgets,[130]
and that cells inside Iraq were required to send up to 20% of the income generated from kidnapping, extortion rackets and other activities to the next level of the group's leadership, which would then redistribute the funds to provincial or local cells that were in difficulties or needed money to conduct attacks.[130]

In mid-2014, Iraqi intelligence obtained information that ISIL had assets worth US$2 billion,[131]
making it the richest jihadist group in the world.[132]
About three-quarters of this sum said to looted from Mosul's central bank and commercial banks in Mosul.[133][134]
However, doubt was later cast on whether ISIL was able to retrieve anywhere near that sum from the central bank,[135]
and even on whether the bank robberies had actually occurred.[136]

Since 2012, ISIL has produced annual reports giving numerical information on its operations, somewhat in the style of corporate reports, seemingly in a bid to encourage potential donors.[107][137]

According to some observers, ISIL emerged from the ideology of the
Muslim Brotherhood, the first
post-Ottoman
Islamist group dating back to the late 1920s in Egypt.[149]
It adheres to global jihadist
principles and follows the hard-line ideology of al-Qaeda
and many other modern-day jihadist groups.[4][9]
However, other sources trace the group's roots to Wahhabism.

For their guiding principles, the leaders of the Islamic State ... are open and clear about their almost exclusive commitment to the Wahhabi movement of Sunni Islam. The group circulates images of Wahhabi religious textbooks from Saudi Arabia in the schools it controls. Videos from the group's territory have shown Wahhabi texts plastered on the sides of an official missionary van.

According to
The Economist, dissidents in the ISIL capital of
Al-Raqqah
report that "all 12 of the judges who now run its court system ... are Saudis". Saudi Wahhabi practices also followed by the group include the establishment of religious police
to root out "vice" and enforce attendance at salat
prayers, the widespread use of capital punishment, and the destruction or re-purposing of any non-Sunni religious buildings.[150]Bernard Haykel
has described al-Baghdadi's creed as "a kind of untamed Wahhabism".[13]

ISIL aims to return to the early days of Islam, rejecting all
innovations
in the religion, which it believes corrupts its original spirit. It condemns later caliphates and the Ottoman Empire
for deviating from what it calls pure Islam,[151]
and seeks to revive the original Wahhabi project of the restoration of the caliphate governed by strict Salafist doctrine. Following Salafi-Wahhabi tradition, ISIL condemns the followers of secular law as disbelievers, putting the current Saudi Arabian government in that category.[42]

Salafists such as ISIL believe that only a legitimate authority can undertake the leadership of
jihad, and that the first priority over other areas of combat, such as fighting non-Muslim countries, is the purification of Islamic society. For example, ISIL regards the Palestinian Sunni group
Hamas
as apostates who have no legitimate authority to lead jihad and see fighting Hamas as the first step toward confrontation by ISIL with Israel.[13][152]

Eschatology

One difference between ISIL and other Islamist and jihadist movements, including
al-Qaeda, is the group's emphasis on
eschatology
and apocalypticism
– that is, a belief in a final Day of Judgment
by God, and specifically, a belief that the arrival of one known as Imam Mahdi
is near. ISIL believes that it will defeat the army of "Rome" at the town of Dabiq, in fulfilment of prophecy.[153]
Following its interpretation of the Hadith of the Twelve Successors, ISIL also believes that after al-Baghdadi there will be only four more legitimate caliphs.[153]

References to the End Times fill Islamic State propaganda. It's a big selling point with foreign fighters, who want to travel to the lands where the final battles of the apocalypse will take place. The civil wars raging in those countries today [Iraq and Syria] lend credibility to the prophecies. The Islamic State has stoked the apocalyptic fire. [...] For Bin Laden's generation, the apocalypse wasn't a great recruiting pitch. Governments in the Middle East two decades ago were more stable, and sectarianism was more subdued. It was better to recruit by calling to arms against corruption and tyranny than against the Antichrist. Today, though, the apocalyptic recruiting pitch makes more sense than before.

Goals and strategy

Goals

Since at least 2004, a significant goal of the group has been the foundation of a
SunniIslamic state.[155][156]
Specifically, ISIL has sought to establish itself as a caliphate, an Islamic state led by a group of religious authorities under a supreme leader – the
caliph
– who is believed to be the successor to Prophet Muhammad.[157]
In June 2014, ISIL published a document in which it claimed to have traced the lineage of its leader al-Baghdadi back to Muhammad,[157]
and upon proclaiming a new caliphate on 29 June, the group appointed al-Baghdadi as its caliph. As caliph, he demands the allegiance of all devout Muslims worldwide, according to Islamic jurisprudence (fiqh).[158]

ISIL has detailed its goals in its
Dabiq
magazine, saying it will continue to seize land and take over the entire Earth until its:

Blessed flag...covers all eastern and western extents of the Earth, filling the world with the truth and justice of Islam and putting an end to the falsehood and tyranny of jahiliyyah [state of ignorance], even if American and its coalition despise such.

According to German journalist
Jürgen Todenhöfer, who spent ten days embedded with ISIL in Mosul, the view he kept hearing was that ISIL wants to "conquer the world", and that all who do not believe in the group's interpretation of the
Quran
will be killed. Todenhöfer was struck by the ISIL fighters' belief that "all religions who agree with democracy have to die",[160]
and by their "incredible enthusiasm" – including enthusiasm for killing "hundreds of millions" of people.[161]

A map was circulated around the internet purporting to show historical areas of former Muslim states in Europe, Asia, and Africa into which ISIL planned to expand. The map was created by outside supporters and has no official connection to ISIL.[151][162][163][164]

When the caliphate was proclaimed, ISIL stated: "The legality of all emirates, groups, states and organisations becomes null by the expansion of the khilafah's [caliphate's] authority and arrival of its troops to their areas."[157]
This was a rejection of the political divisions in Southwestern Asia
that were established by European countries during World War I
in the Sykes–Picot Agreement.[165][166][167]

Strategy

Documents found after the death of Samir Abd Muhammad al-Khlifawi, a former colonel in the intelligence service of
Saddam Hussein's
air defence force who had been called "the strategic head" of ISIL, detailed planning for the ISIL takeover of northern Syria which made possible "the group's later advances into Iraq". Al-Khlifawi called for the infiltration of areas to be conquered with spies who would find out "as much as possible about the target towns: Who lived there, who was in charge, which families were religious, which Islamic school of religious jurisprudence they belonged to, how many mosques there were, who the imam was, how many wives and children he had and how old they were". Following this surveillance and espionage would come murder and kidnapping – "the elimination of every person who might have been a potential leader or opponent". In Al-Raqqah, after rebel forces drove out the Assad regime and ISIL infiltrated the town, "first dozens and then hundreds of people disappeared".
[171]

Security and intelligence expert Martin Reardon has described ISIL's purpose as being to psychologically "break" those under its control, "[...] so as to ensure their absolute allegiance through fear and intimidation," while generating, "[...]outright hate and vengeance" among its enemies.[172]Jason Burke, a journalist writing on
Salafi jihadism, has written that ISIL's goal is to "terrorize, mobilize [and] polarize".[173][174]
Its efforts to terrorise are intended to intimidate civilian populations and force governments of the target enemy "to make rash decisions that they otherwise would not choose". It aims to mobilise its supporters by motivating them with, for example, spectacular deadly attacks on enemy soil such as the November 2015 Paris attacks, to polarise by driving Muslim populations – particularly in the West – away from their governments, thus increasing the appeal of ISIL's self-proclaimed caliphate among them, and to: "Eliminate neutral parties through either absorption or elimination".[173][175]
Journalist Rukmini Maria Callimachi
also emphasises ISIL's interest in polarization or in eliminating what it calls the "grey zone" between the black (non-Muslims) and white (ISIL). "The gray is moderate Muslims who are living in the West and are happy and feel engaged in the society here."[176]

A work published online in 2004 entitled
Management of Savagery[177]
(Idarat at Tawahoush), described by several media outlets as influential on ISIL[178][179][180]
and intended to provide a strategy to create a new Islamic caliphate,[181]
recommended a strategy of attack outside its territory in which fighters would, "Diversify and widen the vexation strikes against the Crusader-Zionist enemy in every place in the Islamic world, and even outside of it if possible, so as to disperse the efforts of the alliance of the enemy and thus drain it to the greatest extent possible."[182]

In August 2011, following the outbreak of the
Syrian Civil War, ISI, under the leadership of al-Baghdadi, delegated a mission into Syria, which under the name
Jabhat an-Nuṣrah li-Ahli ash-Shām
(or al-Nusra Front) established a large presence in Sunni-majority
Al-Raqqah,
Idlib,
Deir ez-Zor, and
Aleppo
provinces. In April 2013, al-Baghdadi decreed the reunification of the Syrian al-Nusra Front with ISI to form the "Islamic State of Iraq and the Levant" (ISIL). However, Abu Mohammad al-Julani
and Ayman al-Zawahiri, the leaders of al-Nusra and al-Qaeda respectively, rejected the merger. After an eight-month power struggle, al-Qaeda cut all ties with ISIL by February 2014, citing its failure to consult and "notorious intransigence".[4][185]

Following the
2003 invasion of Iraq, the Jordanian
Salafi jihadistAbu Musab al-Zarqawi
and his militant group Jama'at al-Tawhid wal-Jihad, founded in 1999, achieved notoriety in the early stages of the Iraqi insurgency
for their suicide attacks
on Shia
mosques, civilians, Iraqi government institutions and Italian soldiers partaking in the US-led 'Multi-National Force'.
Al-Zarqawi's group officially pledged allegiance to Osama bin Laden's
al-Qaeda
network in October 2004, changing its name to Tanzim Qaidat al-Jihad fi Bilad al-Rafidayn (تنظيم قاعدة الجهاد في بلاد الرافدين, "Organisation of Jihad's Base in
Mesopotamia"), also known as
al-Qaeda in Iraq
(AQI).[2][186][187]
Attacks by the group on civilians, Iraqi government and security forces, foreign diplomats and soldiers, and American convoys continued with roughly the same intensity. In a letter to al-Zarqawi in July 2005, al-Qaeda's then deputy leader Ayman al-Zawahiri
outlined a four-stage plan to expand the Iraq War. The plan included expelling
US forces
from Iraq, establishing an Islamic authority as a caliphate, spreading the conflict to Iraq's secular neighbours, and clashing with Israel, which the letter said, "[...] was established only to challenge any new Islamic entity".[188]

In January 2006, AQI joined with several smaller Iraqi insurgent groups under an umbrella organisation called the Mujahideen Shura Council (MSC). According to counterterrorism researcher Brian Fishman, the merger was an attempt to give the group a more Iraqi flavour, and perhaps to distance al-Qaeda from some of al-Zarqawi's tactical errors, more notably the
2005 bombings
by AQI of three hotels in Amman.[189]
On 7 June 2006, a US airstrike killed al-Zarqawi, who was succeeded as leader of the group by the Egyptian militant Abu Ayyub al-Masri.[190][191]

On 12 October 2006, the Mujahideen Shura Council united with three smaller groups and six
Sunni
tribes to form the "Mutayibeen Coalition". It pledged "To rid Sunnis from the oppression of the rejectionists (Shi'ite Muslims) and the crusader occupiers ... to restore rights even at the price of our own lives ... to make Allah's word supreme in the world, and to restore the glory of Islam".[192][193]
A day later, the Mujahideen Shura Council declared the establishment of the Islamic State of Iraq (ISI), comprising Iraq's six mostly Sunni Arab governorates.[194]Abu Omar al-Baghdadi
was announced as its emir,[183][195]
and al-Masri was given the title of Minister of War within the ISI's ten-member cabinet.[196]

The
Iraq War troop surge of 2007
supplied the United States military
with more manpower for operations targeting the group, resulting in dozens of high-level AQI members being captured or killed.[202]
Between July and October 2007, al-Qaeda in Iraq was reported to have lost its secure military bases in Al Anbar province and the Baghdad
area.[203]
During 2008, a series of US and Iraqi offensives managed to drive out AQI-aligned insurgents from their former safe havens, such as the Diyala
and Al Anbar governorates, to the area of the northern city of Mosul.[204]

By 2008, the ISI was describing itself as being in a state of "extraordinary crisis".[205]
Its violent attempts to govern territory led to a backlash from Sunni Arab Iraqis and other insurgent groups and a temporary decline in the group, which was attributable to a number of factors,[206]
notably the Anbar Awakening.

In late 2009, the commander of US forces in Iraq,
General Ray Odierno, stated that the ISI "has transformed significantly in the last two years. What once was dominated by foreign individuals has now become more and more dominated by Iraqi citizens".[207]
On 18 April 2010, the ISI's two top leaders, Abu Ayyub al-Masri
and Abu Omar al-Baghdadi, were killed in a joint US-Iraqi raid near
Tikrit.[208]
In a press conference in June 2010, General Odierno reported that 80% of the ISI's top 42 leaders, including recruiters and financiers, had been killed or captured, with only eight remaining at large. He said that they had been cut off from al-Qaeda's leadership in Pakistan.[209][210][211]

In July 2012, al-Baghdadi released an audio statement online announcing that the group was returning to former strongholds from which US troops and the
Sons of Iraq
had driven them in 2007 and 2008.[219]
He declared the start of a new offensive in Iraq called Breaking the Walls, aimed at freeing members of the group held in Iraqi prisons.[219]
Violence in Iraq had begun to escalate in June 2012, primarily with AQI's car bomb attacks, and by July 2013, monthly fatalities exceeded 1,000 for the first time since April 2008.[220]

Syrian Civil War

In March 2011, protests began in Syria against the Syrian government of
Bashar al-Assad. In the following months, violence between demonstrators and security forces led to a gradual militarisation of the conflict.[221]
In August, al-Baghdadi began sending Syrian and Iraqi ISI members experienced in guerilla warfare
across the border into Syria to establish an organisation there. Led by a Syrian known as Abu Muhammad al-Julani, this group began to recruit fighters and establish cells throughout the country.[222][223]
In January 2012, the group announced its formation as Jabhat al-Nusra li Ahl as-Sham
– Jabhat al-Nusra
– more commonly known as the al-Nusra Front. Al-Nusra grew rapidly into a capable fighting force, with popular support among Syrians opposed to the Assad government.[222]

As
Islamic State of Iraq and the Levant, 2013–14

On 8 April 2013, al-Baghdadi released an audio statement in which he announced that the al-Nusra Front had been established, financed, and supported by the Islamic State of Iraq,[224]
and that the two groups were merging under the name "Islamic State of Iraq and Al-Sham".[225]
Al-Julani issued a statement denying the merger, and complaining that neither he nor anyone else in al-Nusra's leadership had been consulted about it.[226]
In June 2013, Al Jazeera
reported that it had obtained a letter written by al-Qaeda's leader Ayman al-Zawahiri, addressed to both leaders, in which he ruled against the merger, and appointed an emissary to oversee relations between them to put an end to tensions.[227]
That same month, al-Baghdadi released an audio message rejecting al-Zawahiri's ruling and declaring that the merger was going ahead.[228]

Meanwhile, the ISIL campaign to free its imprisoned members culminated in simultaneous raids on
Taji
and Abu Ghraib
prisons in July 2013, freeing more than 500 prisoners, many of them veterans of the Iraqi insurgency.[220][229]
In October 2013, al-Zawahiri ordered the disbanding of ISIL, putting al-Nusra Front in charge of jihadist efforts in Syria,[230]
but al-Baghdadi contested al-Zawahiri's ruling on the basis of Islamic jurisprudence,[228]
and his group continued to operate in Syria. In February 2014, after an eight-month power struggle, al-Qaeda disavowed any relations with ISIL.[185]

According to journalist Sarah Birke, there are "significant differences" between al-Nusra Front and ISIL. While al-Nusra actively calls for the overthrow of the Assad government, ISIL "tends to be more focused on establishing its own rule on conquered territory". ISIL is "far more ruthless" in building an Islamic state, "carrying out sectarian attacks and imposing sharia law immediately". While al-Nusra has a "large contingent of foreign fighters", it is seen as a home-grown group by many Syrians; by contrast, ISIL fighters have been described as "foreign 'occupiers'" by many Syrian refugees.[231]
It has a strong presence in central and northern Syria, where it has instituted sharia
in a number of towns.[231]
ISIL controls the four towns of Atmeh, al-Bab, Azaz and Jarablus on the Turkish border.[231]
Foreign fighters in Syria include Russian-speaking jihadists who were part of Jaish al-Muhajireen wal-Ansar
(JMA).[232]
In November 2013, the JMA's Chechen leader Abu Omar al-Shishani
swore an oath of allegiance
to al-Baghdadi;[233]
the group then split between those who followed al-Shishani in joining ISIL and those who continued to operate independently in the JMA under new leadership.[234]

In January 2014, rebels affiliated with the
Islamic Front
and the US-trained Free Syrian Army[235]
launched an offensive against ISIL militants in and around the city of Aleppo.[236][237]
In May 2014, Ayman al-Zawahiri ordered the al-Nusra Front to stop its attacks on its rival ISIL.[238][not in citation given]
In June 2014, after continued fighting between the two groups, al-Nusra's branch in the Syrian town of Al-Bukamal
pledged allegiance to ISIL.[239][240]
In mid-June 2014, ISIL captured the Trabil crossing on the Jordan–Iraq border,[241]
the only border crossing between the two countries.[242]
ISIL has received some public support in Jordan, albeit limited, partly owing to state repression there.[243]
ISIL has undertaken a recruitment drive in Saudi Arabia,[244]
where tribes in the north are linked to those in western Iraq and eastern Syria.[245]

On 29 June 2014, the organisation proclaimed itself to be a
worldwide caliphate.[246]
Abu Bakr al-Baghdadi – known by his supporters as Amir al-Mu'minin, Caliph Ibrahim – was named its
caliph, and the group renamed itself ad-Dawlah al-Islāmiyah (الدولة الإسلامية,
"Islamic State" (IS)).[54]
As a "Caliphate", it claims religious, political and military authority over all Muslims worldwide.[56]
The concept of it being a caliphate and the name "Islamic State" have been rejected by governments and Muslim leaders worldwide.[247][248][249][250][251][252][253]

In June and July 2014, Jordan and Saudi Arabia moved troops to their borders with Iraq, after Iraq lost control of, or withdrew from, strategic crossing points that then came under the control of ISIL, or tribes that supported ISIL.[242][254]
There was speculation that Iraqi Prime Minister Nouri al-Maliki
had ordered a withdrawal of troops from the Iraq–Saudi crossings in order "to increase pressure on Saudi Arabia and bring the threat of ISIS over-running its borders as well".[245]

Capture of territory

Yazidi refugees and American aid workers on Mount Sinjar in August 2014

On 3 August 2014, ISIL captured the cities of
Zumar,
Sinjar, and
Wana
in northern Iraq.[59]
Thousands of Yazidis
fled up Mount Sinjar, fearful of the approaching hostile ISIL militants. The stranded Yazidis' need for food and water, the threat of
genocide
to them and to others announced by ISIL, along with the desire to protect US citizens in Iraq and support Iraq in its fight against ISIL, were all reasons given for the 2014 American intervention in Iraq
on 7 August[258]
and an aerial bombing campaign
in Iraq which started on 8 August.

At the end of October 2014, 800 militants gained partial control of the Libyan city of
Derna
and pledged their allegiance to Abu Bakr al-Baghdadi, thus making Derna the first city outside Syria and Iraq to be a part of the "Islamic State Caliphate".[259]
On 10 November 2014, a major faction of the Egyptian militant group Ansar Bait al-Maqdis
also pledged its allegiance to ISIL.[260]
In mid-January 2015, a Yemeni official said that ISIL had "dozens" of members in Yemen, and that they were coming into direct competition with al-Qaeda in the Arabian Peninsula
with their recruitment drive.[261]
Also in January 2015, Afghan officials confirmed that ISIL had a military presence in Afghanistan.[262]
However, by February 2015, 65 of the militants were either captured or killed by the Taliban, and ISIL's top Afghan recruiter,
Mullah Abdul Rauf, was killed in a
US drone strike.[263][264][265]

In early February 2015, ISIL militants in Libya managed to capture part of the countryside to the west of
Sabha, and later, an area encompassing the cities of
Sirte,
Nofolia, and a military base to the south of both cities. By March, ISIL had captured additional territory, including a city to the west of Derna, additional areas near Sirte, a stretch of land in southern Libya, some areas around
Benghazi, and an area to the east of
Tripoli.

On 7 March 2015,
Boko Haram
swore formal allegiance to ISIL, giving ISIL an official presence in Nigeria, Niger, Chad and Cameroon.[7][266][267]
On 13 March 2015, a group of militants from the Islamic Movement of Uzbekistan
swore allegiance to ISIL;[268]
the group released another video on 31 July 2015 showing its spiritual leader also pledging allegiance.[269]
In June 2015, the US Deputy Secretary of State announced that ISIL had lost more than 10,000 members in airstrikes over the preceding nine months.[270][271]

Aftermath of ISIL-occupation

On 30 August 2016, a survey conducted by the
Associated Press
found that forces present in Iraq and Syria had discovered around 72 mass graves in areas that have been liberated from ISIL control. In total, these mass graves contain the bodies of approximately 15,000 people killed by ISIL in both countries. A report stated that the mass graves were evidence of genocides conducted by ISIL in the region, including the genocide of Yazidis. Seventeen graves were discovered in Syria, with the rest being found in Iraq. At least 16 of the graves in Iraq contained remains that were not counted, as they are located in dangerous conflict zones. Instead, the number of dead in these graves has been estimated.[277]

Territorial claims and international presence

Areas controlled during late 2015 peak Remaining territory in countries with ISIL presence

As a self-proclaimed worldwide
caliphate, ISIL claims religious, political and military authority over all Muslims worldwide,[56]
and that "the legality of all emirates, groups, states, and organisations, becomes null by the expansion of the khilāfah's [caliphate's] authority and arrival of its troops to their areas".[157]

In Iraq and Syria, ISIL uses many of those countries' existing
governorate boundaries
to subdivide its claimed territory; it calls these divisions wilayah
or provinces.[278]
As of June 2015, it had established official branches in Libya, Egypt (Sinai Peninsula), Saudi Arabia, Yemen, Algeria, Afghanistan, Pakistan, Nigeria and the North Caucasus.[279]
Outside Iraq and Syria, it controls territory
only in Sinai, Afghanistan, and Libya.[63]
ISIL also has members in Morocco, Lebanon, Jordan, Turkey, and Israel, but does not have official branches in those areas.[280]

On 5 October 2014, the Shura Council of Islamic Youth and other militants in Libya were absorbed and designated the Cyrenaica Province of ISIL.[282][283]
The Libyan branch of ISIL has been the most active and successful of all ISIL branches outside Iraq and Syria. It has been active mainly around Derna
and Gaddafi's hometown
Sirte.[284][285]

On 4 January 2015, ISIL forces in Libya seized control of the eastern countryside of
Sabha, executing 14 Libyan soldiers in the process.[286][287]
They temporarily controlled part of Derna
before being driven out in mid-2015 by a rival militant Islamist group, with support from the Libyan Air Force.[288][289]
Reports from Sirte suggest ISIL militants based there are a mixture of foreign fighters and ex-Gaddafi
loyalists.[290]
An initiative between pro-Dawn forces associated with Misrata and Operation Dawn clashed with these IS militants in Sirte.[citation needed][291][292]
Fighting between Libya Dawn forces and ISIL militants was also reported in the Daheera area west of the city of Sirte, and at the Harawa vicinity east of Sirte.[293]
The Libyan National Army, led by Commander General
Khalifa Haftar, has also clashed with ISIL, making advances against the group in
Benghazi
and Ajdabiya.[294][295][296]

Sinai Province

On 10 November 2014, many members of the group
Ansar Bait al-Maqdis
took an oath of allegiance to al-Baghdadi.[260]
Following this, the group assumed the designation Sinai Province
(Wilayat Sinai).[282][299][300][301]
They are estimated to have 1,000–2,000 fighters.[65][302]
A faction of the Sinai group also operates in the Gaza Strip, calling itself the
Islamic State in Gaza.[303]
On 19 August 2015, members of the group bombed an Egyptian security headquarters building in northern Cairo, injuring 30 people.[304]
It is also speculated to be behind the crash of Russian Metrojet Flight 9268, which killed all 224 people on board. The group has claimed responsibility for that attack in audio recordings, although Egyptian officials deny that there is enough evidence for the claim.[305]

Algerian Province

Members of
Jund al-Khilafah
swore allegiance to ISIL in September 2014.[306]
ISIL in Algeria gained notoriety when it beheaded French tourist Herve Gourdel in September 2014. Since then, the group has largely been silent, with reports that its leader Khalid Abu-Sulayman was killed by Algerian forces in December 2014.[279]

Khorasan Province

On 26 January 2015,
Khorasan Province
(Wilayat Khorasan) was established, with Hafiz Saeed Khan named as Wāli
(Governor) and Abdul Rauf
as his deputy after both swore an oath of allegiance to al-Baghdadi. The name Khorasan refers to a historical region that includes Afghanistan, Pakistan, and "other nearby lands".[5][265][307][308]

On 9 February 2015, Mullah Abdul Rauf was killed by a NATO airstrike.[265]
On 18 March 2015, Hafiz Wahidi, ISIL's replacement deputy Emir in Afghanistan, was killed by the Afghan Armed Forces, along with nine other ISIL militants who were accompanying him.[309]
In June, Reuters received reports that villages in several districts of Afghanistan's eastern Nangarhar Province
had been captured from the Taliban by ISIL sympathisers.[63]
On 10 July 2015, Hafiz Saeed Khan, the Emir of ISIL's Khorasan Province, was reportedly killed in a US drone strike in eastern Afghanistan.[310]
However Khorasan Province released an audio tape claimed to be of Hafiz Saeed Khan on 13 July 2015,[311]
and he was sanctioned by the US Department of the Treasury
on 29 September 2015.[312]

Yemen Provinces

On 13 November 2014, unidentified militants in Yemen pledged allegiance to ISIL.[306]
By December of that year, ISIL had built an active presence inside Yemen, with its recruitment drive bringing it into direct competition with al-Qaeda-affiliated al-Qaeda in the Arabian Peninsula
(AQAP).[261][313]
In February 2015, it was reported that some members of Ansar al-Sharia in Yemen
had split from AQAP and pledged allegiance to ISIL.[314]
As the Yemeni Civil War
escalated in March 2015, at least seven ISIL Wilayat, named after existing provincial boundaries in Yemen, claimed responsibility for attacks against the Houthis, including the
Hadhramaut
Province, the
Shabwah
Province, and the
Sana'a
Province.[315][316]

Shi'aHouthis
(Revolutionary Committee) are principal enemies of Yemen's ISIL branch.[317][318]
The US supports the Saudi-led military intervention in Yemen
against the Houthis,[319]
but many in US SOCOM
reportedly favour Houthis, as they have been an effective force in rolling back al-Qaeda and recently ISIL in Yemen, "something that hundreds of U.S. drone strikes and large numbers of advisers to Yemen's military had failed to accomplish".[320]The Guardian
reported: "As another 50 civilians die in the forgotten war, only Isis and al-Qaida are gaining from a conflict tearing Yemen apart and leaving 20 million people in need of aid."[321]

West African Province

On 7 March 2015, Boko Haram's leader
Abubakar Shekau
pledged allegiance to the Islamic State of Iraq and the Levant via an audio message posted on the organisation's Twitter
account.[322][323]
On 12 March 2015, ISIL's spokesman Abu Mohammad al-Adnani
released an audio tape in which he welcomed the pledge of allegiance, and described it as an expansion of the group's caliphate into West Africa.[6]
ISIL publications from late March 2015 began referring to members of Boko Haram as part of Wilayat Gharb Afriqiya
(West Africa Province).[316]

Current name

In April 2013, having expanded into Syria, the group adopted the name
ad-Dawlah al-Islāmiyah fī 'l-ʿIrāq wa-sh-Shām
(الدولة الإسلامية في العراق والشام‎). As
al-Shām
is a region often compared with the Levant
or Greater Syria, the group's name has been variously translated as "Islamic State of Iraq and
al-Sham",[340]
"Islamic State of Iraq and Syria"[341]
(both abbreviated as ISIS), or "Islamic State of Iraq and the Levant" (abbreviated as
ISIL).[39]

While the use of either one or the other
acronym
has been the subject of debate,[39][342]
the distinction between the two and its relevance has been considered not so great.[39]
Of greater relevance is Daesh, an acronym of ISIL's
Arabic
name al-Dawlah al-Islamīyah fī al-ʻIrāq wa-al-Shām.Daesh, or
Da'ish
(داعش‎), has been widely used by ISIL's Arabic-speaking detractors,[clarification needed][343][344]
although – and to a certain extent because – it is considered derogatory, as it resembles the Arabic words Daes
(lit. "one who crushes, or tramples down, something underfoot") and Dāhis
(loosely translated: "one who sows discord").[40][345]
Within areas under its control, ISIL considers use of the acronym Daesh
punishable by flogging[346]
or cutting out the tongue.[347]

In late June 2014 the group renamed itself
ad-Dawlah al-Islāmiyah
(lit. Islamic State
or IS), declaring itself a worldwide
caliphate.[54]
The name "Islamic State" and the group's claim to be a caliphate have been widely rejected, with the UN, various governments, and mainstream Muslim groups refusing to use the new name.[247][248][249][250][251][252][253][348]

Supporters

Iraq and Syria nationals

According to a
Reuters
report that cited "jihadist ideologues" as a source, 90% of ISIL's fighters in Iraq are Iraqi, and 70% of its fighters in Syria are Syrian. The article stated that the group has 40,000 fighters and 60,000 supporters across its two primary strongholds in Iraq and Syria.[33]
According to scholar Fawaz Gerges
writing in ISIS: A History, some "30 percent of the senior figures" in ISIL's military command are former army and police officers from the disbanded Iraqi security forces, drawn to ISIL by the US
De-Ba'athification
policy and turn towards Islamism by Sunni following the US invasion of Iraq.[70]

Acceptance among ordinary Muslims

According to a poll by
Pew Research Center, Muslim populations of various countries have overwhelmingly negative views of ISIS with
Lebanon
having the most unfavorable views.[349][350]
In most of these countries, concerns about Islamic extremism have been growing.[351]

Richard Dearlove, former head of Britain's
Secret Intelligence Service
(MI6), said that the Saudis were "deeply attracted to any militancy that can effectively challenge Shia-dom
[Shia version of Islam]."[356]
Dearlove stated that, "For ISIS to be able to surge into the Sunni areas of Iraq in the way that it has done recently has to be the consequence of substantial and sustained funding."[357]

In an August 2014 email, leaked by
WikiLeaks, former US Secretary of State
Hillary Clinton
sent then counselor to Barack Obama John Podesta
a memo that states that both Saudi Arabia and Qatar "are providing clandestine financial and logistic support to ISIL and other radical Sunni groups in the region".[358][359][360]

Syria

During the ongoing
Syrian civil war, President
Bashar al-Assad, the Syrian government, and the Syrian Alawite community
[361]
have been accused by many opposition
and anti-Assad parties of collusion with ISIL, despite massacres of Alawite
civilians and executions of captured Syrian Army
Alawite soldiers,[362][363][364][365][366]
Several sources have claimed Islamist prisoners were strategically released from Syrian prisons at the beginning of the Syrian civil war in 2011.[367]

The Syrian government has bought oil directly from ISIL,[368]
and the Syrian government and ISIL jointly run a HESCO gas plant in Tabqah. The facility supplies electricity to government-held areas, and government-run power plants supply ISIL-held areas.[369]
The Syrian government has tactically avoided ISIL forces in order to weaken opposition such as the Free Syrian Army
(FSA),[366]
and according to United States Secretary of State John Kerry
the Syrian government has purposely ceded territory to ISIL.[370]
An IHS Jane's Terrorism and Insurgency Center
database analysis confirmed that only 6% of Syrian government forces attacks were targeted at ISIL from January to November 2014, while in the same period only 13% of all ISIL attacks targeted government forces.[371]
The National Coalition for Syrian Revolutionary and Opposition Forces
has stated that the Syrian government has operatives inside ISIL,[372]
as has the leadership of Ahrar ash-Sham.[373]
A report on 25 June 2015 said that ISIL kept gas flowing to Assad regime-controlled power stations. Furthermore, ISIL allowed grain to pass from the Kurdish-held north-east to regime controlled areas at the cost of a 25% levy.[374]

On 1 June 2015, the United States embassy in Syria stated that the Syrian government was "making air-strikes in support" of an ISIL advance on Syrian opposition positions north of Aleppo.[375]
The president of the Syrian National Coalition, Khaled Koja, accused Assad of acting "as an air force for [ISIL]",[376]
with the Defence Minister of the SNC Salim Idris
stating that approximately 180 Syrian government officers were serving in ISIL and coordinating the group's attacks with the Syrian Arab Army.[377]

Turkey

Turkey has been accused by experts, Syrian Kurds, and United States Vice-President
Joe Biden
of supporting or colluding with ISIL.[378][379][380]
A raid by US special forces on a compound housing the Islamic State's "chief financial officer", Abu Sayyaf, in July 2015, produced evidence that Turkish officials dealt directly with ranking ISIL members. According to a senior Western official, documents and flash drives seized during the Sayyaf raid revealed links "so clear" and "undeniable" between Turkey and ISIL "that they could end up having profound policy implications for the relationship between us and Ankara".[378]

Journalist
Patrick Cockburn
wrote in November 2014 of "strong evidence for a degree of collaboration" between the Turkish intelligence services
and ISIL, although the "exact nature of the relationship ... remains cloudy".[381]
In July 2014, Cockburn stated that "Saudi Arabia has created a Frankenstein's monster over which it is rapidly losing control. The same is true of its allies such as Turkey which has been a vital back-base for Isis and Jabhat al-Nusra by keeping the 820-kilometer-long (510 mi) Turkish-Syrian border open."[356]
David L. Phillips of Columbia University's Institute for the Study of Human Rights, who compiled a list of allegations and claims accusing Turkey of assisting ISIL, wrrote that these allegations "range from military cooperation and weapons transfers to logistical support, financial assistance, and the provision of medical services".[382]
Several ISIL fighters and commanders have claimed that Turkey supports ISIL.[383][384][385]
Within Turkey itself, ISIL is believed to have caused increasing political polarisation between secularists and Islamists.[386]

Turkey has been further criticised for allowing individuals from outside the region to enter its territory and join ISIL in Syria.[387][388]
With many Islamist fighters passing through Turkey to fight in Syria, Turkey has been accused of becoming a transit country for such fighters and has been labelled the "Gateway to Jihad".[389]
Turkish border patrol officers are reported to have deliberately overlooked those entering Syria, upon payment of a small bribe.[389]
A report by Sky News
exposed documents showing that passports of foreign Islamists wanting to join ISIL by crossing into Syria had been stamped by the Turkish government.[390]
An ISIL commander stated that "most of the fighters who joined us in the beginning of the war came via Turkey, and so did our equipment and supplies",[382][385]
adding that ISIL fighters received treatment in Turkish hospitals.[385]

Qatar

Qatar
has long been accused of acting as a conduit for the flow of funds to ISIL. While there is no proof that the Qatari government is behind the movement of funds from the gas-rich nation to ISIL, it has been criticised for not doing enough to stem the flow of financing. Private donors within Qatar, sympathetic to the aims of radical groups such as al-Nusra Front
and ISIL, are believed to be channeling their resources to support these organisations.[391][392]
According to the US Treasury Department, a number of terrorist financiers have been operating in Qatar. Qatari citizen
Abd Al-Rahman al-Nuaimi
has served as an interlocutor between Qatari donors and leaders of al-Qaeda in Iraq
(AQI). Nuaimi reportedly oversaw the transfer of US$2 million per month to AQI over a period of time. He is also one of several of Qatar-based al-Qaeda financiers sanctioned by the US Treasury in recent years. According to some reports, US officials believe that the largest portion of private donations supporting ISIS and al Qaeda-linked groups now comes from Qatar rather than Saudi Arabia.[393]

In August 2014, a German minister
Gerd Müller
accused Qatar of having links to ISIL, stating: "You have to ask who is arming, who is financing ISIS troops. The keyword there is Qatar." Qatari Foreign Minister Khalid bin Mohammad Al Attiyah
rejected this statement, saying: "Qatar does not support extremist groups, including [ISIL], in any way. We are repelled by their views, their violent methods and their ambitions."[394][395][396][397]

United States

Rand Paul, junior U.S. Senator from Kentucky, has accused the U.S. government of indirectly supporting ISIL in the
Syrian Civil War, by arming their allies and fighting their enemies in that country. The US has assisted the moderate Syrian opposition, but whether that assistance has been commandeered by ISIS allies remains unclear.[398]

In September 12, 2014, several media outlets began reporting that the Free Syrian Army had signed a "non-aggression pact" with ISIS in order to focus their attentions elsewhere.[399][400]
These reports later proved to be false, as opposition soldiers and activists on the ground reported continued fighting between the two groups. According to Mohammed Alaa Ghanem, director of government relations for the Syrian American Council, "The only report we have received on anything resembling a ceasefire was that ISIS and Sons of Golan, an FSA brigade outside Damascus, halted fighting for 24 hours to collect bodies before hostilities resumed."[401]
"FSA commanders declared that they will continue that fight until ISIS is completely eradicated in Damascus suburbs. No truce or cease fire with ISIS," said Syrian National Coalition spokesman Monzer Abkik.[402]

Foreign nationals

A United Nations report from May 2015[update]
showed that 25,000 "foreign terrorist fighters" from 100 countries had joined "Islamist" groups, many of them working for ISIL or al-Qaeda.[403]
The US-trained commander of Tajikistan's
Interior MinistryOMON
police special forces, Gulmurod Khalimov, has been raised to the rank of "Minister of War" within the Islamic State.[30][404]

A 2015 report by the Program on Extremism at George Washington University found 71 individuals charged in the United States with supporting ISIL, 250 travelling or attempting to travel to Syria or Iraq from the United States to join ISIL, and about 900 active domestic ISIL-related investigations.[406]

An October 2016 World Bank study found that "ISIL’s foreign fighters are surprisingly well-educated."[407]
Using the fighters' self-reported educational levels, the study concluded that "69% of recruits reported at least a secondary-level education"[407]
of which "a large fraction have gone on to study at university"[408]
and also that "only 15% of recruits left school before high school; less than 2% are illiterate."[407][408]
The study also found that foreign fighters are often more educated than their countrymen where those "from Europe and in Central Asia have similar levels of education to their countrymen" while those "from the Middle East, North Africa, and South and East Asia are significantly more educated than what is typical in their home nations."[407]
The report notes that its conclusions that terrorism is not driven by poverty and low levels of education does not conform with previous research.[407]
However, the report did find a strong correlation "between a country’s male unemployment rate and the propensity of the country to supply foreign fighters" leading the report to recommend that governments pursue a policy of lowering the unemployment rate among the educated as a counter-terrorism strategy.[407]

Groups expressing support for ISIL

The Terrorism Research and Analysis Consortium (TRAC) has identified 60 jihadist groups in 30 countries that have pledged allegiance to or support for ISIL as of mid-November 2014. That many of these groups were previously affiliated with
al-Qaeda
suggests a shift in global jihadist leadership towards ISIL.[409]

Members of the following groups have declared support for ISIL, either fully or in part:

Human rights abuse and war crime findings

In July 2014, the
BBC
reported the United Nations' chief investigator as stating: "Fighters from the Islamic State in Iraq and the Levant (ISIL) may be added to a list of war crimes suspects in Syria."[425]
By June 2014, according to United Nations reports, ISIL had killed hundreds of prisoners of war[426]
and over 1,000 civilians.

In November 2014, the UN Commission of Inquiry on Syria said that ISIL was committing crimes against humanity.[427][428]
A report by Human Rights Watch
in November 2014 accused ISIL groups in control of Derna, Libya of
war crimes
and human rights abuses
and of terrorising residents. Human Rights Watch documented three apparent summary executions and at least ten public floggings by the Islamic Youth Shura Council, which joined ISIL in November. It also documented the beheading of three Derna residents and dozens of seemingly politically motivated assassinations of judges, public officials, members of the security forces and others. Sarah Leah Watson, Director of HRW Middle East and North Africa, said: "Commanders should understand that they may face domestic or international prosecution for the grave rights abuses their forces are committing."[429]

Speaking of ISIL's methods, the
United Nations Commission on Human Rights
has stated that the group "seeks to subjugate civilians under its control and dominate every aspect of their lives through terror, indoctrination, and the provision of services to those who obey".[83]

Amnesty International
has held ISIL responsible for the ethnic cleansing
of ethnic and religious minority groups in northern Iraq on a "historic scale", putting entire communities "at risk of being wiped off the map of Iraq". In a special report released on 2 September 2014, the organization described how ISIL had "systematically targeted non-Arab and non-Sunni Muslim communities, killing or abducting hundreds, possibly thousands, of individuals and forcing more than 830,000 others to flee the areas it has captured since 10 June 2014". Among these people were Assyrian Christians, Turkmen Shia, Shabak Shia, Kaka'i, Yazidis and Sabean Mandeans, who have lived together for centuries in
Nineveh
province, large parts of which have come under ISIL's control.[52][435]

Among the known killings of religious and minority group civilians carried out by ISIL are those in the villages and towns of Quiniyeh (70–90 Yazidis killed), Hardan (60 Yazidis killed),
Sinjar
(500–2,000 Yazidis killed), Ramadi Jabal (60–70 Yazidis killed), Dhola (50 Yazidis killed), Khana Sor (100 Yazidis killed), Hardan
(250–300 Yazidis killed), al-Shimal (dozens of Yazidis killed), Khocho (400 Yazidis killed and 1,000 abducted), Jadala
(14 Yazidis killed)[436]
and Beshir (700 Shia Turkmen killed),[437]
and others committed near Mosul (670 Shia inmates of the Badush prison killed),[437]
and in Tal Afar
prison, Iraq (200 Yazidis killed for refusing conversion).[436]
The UN estimated that 5,000 Yazidis were killed by ISIL during the takeover of parts of northern Iraq in August 2014.[438]
In late May 2014, 150 Kurdish boys from Kobani
aged 14–16 were abducted and subjected to torture and abuse, according to Human Rights Watch.[439]
In the Syrian towns of Ghraneij, Abu Haman and Kashkiyeh 700 members of the Sunni Al-Shaitat
tribe were killed for attempting an uprising against ISIL control.[440][441]
The UN reported that in June 2014 ISIL had killed a number of Sunni Islamic clerics who refused to pledge allegiance to it.[432]

Christians living in areas under ISIL control faced four options: converting to Islam, paying a religious levy or
jizya, leaving the "caliphate", or death.[442][443]
"We offer them three choices: Islam; the dhimma
contract – involving payment of jizya; if they refuse this they will have nothing but the sword", ISIL said.[444][445]
ISIL leader Abu Bakr al-Baghdadi
further noted that Christians who do not agree with those terms must "leave the borders of the Islamic Caliphate" within a specified deadline.[444][445]
ISIL had already set similar rules for Christians in Al-Raqqah, once one of Syria's more liberal cities.[446][447]
However, on 29 March 2016, ISIL issued a decree preventing Christians and Armenians from leaving Al-Raqqah.[448]

On 23 February 2015, in response to a major Kurdish offensive in the
Al-Hasakah Governorate, ISIL abducted 150
Assyrian
Christians from villages near Tal Tamr (Tell Tamer) in northeastern Syria, after launching a large offensive in the region.[449][450]

Kurdish officials have claimed that
ISIL's campaign
against Kurdish and Yezidi enclaves, such as Sinjar, are part of an organised Arabization plan.[451]

Treatment of civilians

During the Iraqi conflict in 2014, ISIL released dozens of videos showing its ill treatment of civilians, many of whom had apparently been targeted on the basis of their religion or ethnicity. Navi Pillay, UN High Commissioner for Human Rights, warned of war crimes being committed in the Iraqi war zone, and disclosed a UN report of ISIL militants murdering Iraqi Army soldiers and 17 civilians in a single street in Mosul. The UN reported that in the 17 days from 5 to 22 June, ISIL killed more than 1,000 Iraqi civilians and injured more than 1,000.[452][453][454]
After ISIL released photographs of its fighters shooting scores of young men, the UN declared that cold-blooded "executions" by militants in northern Iraq almost certainly amounted to war crimes.[455]

ISIL's advance in Iraq in mid-2014 was accompanied by continuing violence in Syria. On 29 May, ISIL raided a village in Syria and at least 15 civilians were killed, including, according to Human Rights Watch, at least six children.[456]
A hospital in the area confirmed that it had received 15 bodies on the same day.[457]
The Syrian Observatory for Human Rights
reported that on 1 June, a 102-year-old man was killed along with his whole family in a village in Hama
province.[458]
According to Reuters, 1,878 people were killed in Syria by ISIL during the last six months of 2014, most of them civilians.[459]

In Mosul, ISIL has implemented a
sharia
school curriculum which bans the teaching of art, music, national history, literature and Christianity. Although
Charles Darwin's theory of evolution
has never been taught in Iraqi schools, the subject has been banned from the school curriculum. Patriotic songs have been declared blasphemous, and orders have been given to remove certain pictures from school textbooks.[460][461][462][463]
Iraqi parents have largely boycotted schools in which the new curriculum has been introduced.[464]

After capturing cities in Iraq, ISIL issued guidelines on how to wear clothes and veils. ISIL warned women in the city of Mosul to wear full-face veils or face severe punishment.[465]
A cleric told Reuters in Mosul that ISIL gunmen had ordered him to read out the warning in his mosque when worshippers gathered. ISIL ordered the faces of both male and female mannequins to be covered, in an order which also banned the use of naked mannequins.[466]
In Al-Raqqah
the group uses its two battalions of female fighters in the city to enforce compliance by women with its strict laws on individual conduct.[467]

ISIL released 16 notes labelled "Contract of the City", a set of rules aimed at civilians in
Nineveh. One rule stipulated that women should stay at home and not go outside unless necessary. Another rule said that stealing would be punished by amputation.[468][469]
In addition to the Muslim custom of banning the sale and use of alcohol, ISIL has banned the sale and use of cigarettes and hookah
pipes. It has also banned "music and songs in cars, at parties, in shops and in public, as well as photographs of people in shop windows".[470]

According to
The Economist, Saudi practices also followed by the group include the establishment of
religious police
to root out "vice" and enforce attendance at salat
prayers, the widespread use of capital punishment, and the destruction of Christian churches and non-Sunni mosques or their conversion to other uses.[150]

The Islamic State militants were accused of using civilian residents of towns as
human shields.[477]
The Telegraph
reported that "Extremist fighters are deliberately hiding among civilian buildings and residents to try to prevent strikes."[478][479]
Civil rights activist told ARA News that "ISIS militants prevent the people of Manbij and Jarablus from leaving their hometowns despite the fierce airstrikes by Russian warplanes".[480]

Child soldiers

According to a report by the magazine
Foreign Policy, children as young as six are recruited or kidnapped and sent to military and religious training camps, where they practice beheading with dolls and are indoctrinated with the religious views of ISIL.[481]
Children are used as human shields on front lines and to provide blood transfusions for Islamic State soldiers,[481]
according to Shelly Whitman of the Roméo Dallaire Child Soldiers Initiative. The second instalment of a Vice News
documentary about ISIL focused on how the group is specifically grooming children for the future. A spokesman told VICE News that those under the age of 15 go to sharia
camp to learn about religion, while those older than 16 can go to military training camp.[481]
Children are also used for propaganda. According to a UN report, "In mid-August, ISIL entered a cancer hospital in Mosul, forced at least two sick children to hold the ISIL flag and posted the pictures on the internet." Misty Buswell, a Save the Children
representative working with refugees in Jordan, said, "It's not an exaggeration to say we could lose a whole generation of children to trauma."[482]
A UN report indicated that at least 89 children, mostly from the ages of 12 to 16 had been killed fighting for the Islamic State in 2015, 39% of which died in suicide bombing attacks.[483]
Der Spiegel estimated in 2016 that 1,500 boys were serving as child soldiers for ISIL.[481]

There are many reports of sexual abuse and enslavement in ISIL-controlled areas of women and girls, predominantly from the minority Christian and Yazidi communities.[487][488]
Fighters are told that they are free to have sex with or rape non-Muslim captive women.[489]
Haleh Esfandiari from the Woodrow Wilson International Center for Scholars
has highlighted the abuse of local women by ISIL militants after they have captured an area. "They usually take the older women to a makeshift slave market and try to sell them. The younger girls ... are raped or married off to fighters", she said, adding, "It's based on temporary marriages, and once these fighters have had sex with these young girls, they just pass them on to other fighters."[490]

The capture of Iraqi cities by the group in June 2014 was accompanied by an upsurge in
crimes against women, including kidnap and rape.[491][492][493]
According to Martin Williams in The Citizen, some hard-line
Salafists
apparently regard extramarital sex with multiple partners as a legitimate form of holy war
and it is "difficult to reconcile this with a religion where some adherents insist that women must be covered from head to toe, with only a narrow slit for the eyes".[494]

As of August 2015, the trade in sex slaves appeared to remain restricted to Yazidi women and girls.[486]
It has reportedly become a recruiting technique to attract men from conservative Muslim societies, where dating and casual sex are not allowed.[486]Nazand Begikhani
said of the Yazidi victims, "These women have been treated like cattle ... They have been subjected to physical and sexual violence, including systematic rape and sex slavery. They've been exposed in markets in Mosul and in Raqqa, Syria, carrying price tags."[495]
According to UN Reports the price list for IS sex slaves range from 40 to 160 US dollars. The younger the slave the more expensive. Girls and boys between the age 1–9 are referred to as the most expensive, with the cheapest being women between 40 and 50 years old.[496]
According to another source the price of a slave equals the price of an AK-47.[497]

A United Nations report issued on 2 October 2014, based on 500 interviews with witnesses, said that ISIL took 450–500 women and girls to Iraq's
Nineveh
region in August, where "150 unmarried girls and women, predominantly from the Yazidi and Christian communities, were reportedly transported to Syria, either to be given to ISIL fighters as a reward or to be sold as sex slaves".[488]
In mid-October, the UN confirmed that 5,000–7,000 Yazidi women and children had been abducted by ISIL and sold into slavery.[438][498]
In November 2014 The New York Times
reported on the accounts given by five who escaped ISIL of their captivity and abuse.[499]
In December 2014, the Iraqi Ministry of Human Rights
announced that ISIL had killed over 150 women and girls in Fallujah
who refused to participate in sexual jihad.[500][501]
Non-Muslim women have reportedly been married off to fighters against their will. ISIL claims the women provide the new converts and children necessary to spread ISIL's control.[502]

In its digital magazine
Dabiq, ISIL explicitly claimed religious justification for enslaving Yazidi women.[512][513][514]
According to The Wall Street Journal, ISIL appeals to
apocalyptic beliefs
and claims "justification by a Hadith that they interpret as portraying the revival of slavery as a precursor to the end of the world".[515]
ISIL appeals to the hadith
and Quran
when claiming the right to enslave and rape captive non-Muslim women.[512][516][517]
According to Dabiq,
"enslaving the families of the kuffar
and taking their women as concubines is a firmly established aspect of the Sharia's that if one were to deny or mock, he would be denying or mocking the verses of the Quran and the narration of the Prophet ... and thereby apostatizing from Islam." Captured Yazidi women and children are divided among the fighters who captured them, with one fifth taken as a tax.[517][518]
ISIL has received widespread criticism from Muslim scholars and others in the Muslim world for using part of the Quran to derive a ruling in isolation, rather than considering the entire Quran and hadith.[512][516][517]
According to Mona Siddiqui, ISIL's "narrative may well be wrapped up in the familiar language of jihad and 'fighting in the cause of Allah', but it amounts to little more than destruction of anything and anyone who doesn't agree with them"; she describes ISIL as reflecting a "lethal mix of violence and sexual power" and a "deeply flawed view of manhood".[502]Dabiq
describes "this large-scale enslavement" of non-Muslims as "probably the first since the abandonment of Shariah law".[517][518]

In late 2014, ISIL released a pamphlet that focused on the treatment of female slaves.[519][520]
It claims that the Quran
allows fighters to have sex with captives, including adolescent girls, and to beat slaves as discipline. The pamphlet's guidelines also allow fighters to trade slaves, including for sex, as long as they have not been impregnated by their owners.[519][520][521]
Charlie Winter, a researcher at the counter-extremist think tankQuilliam, described the pamphlet as "abhorrent".[521][522]
In response to this document Abbas Barzegar, a religion professor at Georgia State University, said Muslims around the world find ISIL's "alien interpretation of Islam grotesque and abhorrent".[523]
Muslim leaders and scholars from around the world have rejected the validity of ISIL's claims, claiming that the reintroduction of slavery is un-Islamic, that they are required to protect "People of the Scripture" including Christians, Jews, Muslims and Yazidis, and that ISIL's fatwas are invalid due to their lack of religious authority and the fatwas' inconsistency with Islam.[524][525]

The Independent
reported in 2015 that the usage of Yazidi sex slaves had created ongoing friction among fighters within ISIL. Sajad Jiyad, a Research Fellow and Associate Member at the Iraqi Institute for Economic Reform, told the newspaper that many ISIL supporters and fighters had been in denial about the trafficking of kidnapped Yazidi women until a
Dabiq
article justifying the practice was published.[526][527]The New York Times
said in August 2015 that "[t]he systematic rape of women and girls from the Yazidi religious minority has become deeply enmeshed in the organization and the radical theology of the Islamic State in the year since the group announced it was reviving slavery as an institution."[486]
The article claims that ISIL is not merely exonerating but sacralising rape, and illustrated this with the testimony of escapees. One 15-year-old victim said that, while she was being assaulted, her rapist "kept telling me this is ibadah"; a 12-year-old victim related how her assailant claimed that, "by raping me, he is drawing closer to God";[486]
and one adult prisoner told how, when she challenged her captor about repeatedly raping a 12 year old, she was met with the retort, "No, she's not a little girl, she's a slave and she knows exactly how to have sex and having sex with her pleases God."[486]

In July 2016 it was reported by an
AP
investigation that ISIL was using mobile apps like Telegram to sell their sex slaves and identify the slaves of other ISIL members at checkpoints.[528]
In 2016 the Commission for International Justice and Accountability said they had identified 34 senior ISIL members who were instrumental in the systematic sex slave trade and planned to prosecute them after the end of hostilities.[529]

In December 2013, two suicide bombers stormed the headquarters of TV station Salaheddin and killed five journalists, after accusing the station of "distorting the image of Iraq's Sunni community". Reporters Without Borders reported that on 7 September 2014, ISIL seized and on 11 October publicly beheaded Raad al-Azzawi, a TV Salaheddin cameraman from the village of Samra, east of Tikrit.[534]
As of October 2014, according to the Journalistic Freedoms Observatory, ISIL is holding nine journalists and has nine others under close observation in Mosul and Salahuddin province.[533]

During 2013 and part of 2014, an ISIL unit nicknamed
the Beatles
acquired and held 12 Western journalists hostage, along with aid workers and other foreign hostages, totalling 23 or 24 known hostages. A Polish journalist Marcin Suder was captured in July 2013 but escaped four months later.[535]
The unit executed American journalists
James Foley and Steven Sotloff and released beheading videos. Eight of the other journalists were released for ransom: Danish journalist Daniel Rye Ottosen, French journalists Didier François, Edouard Elias, Nicolas Hénin, and Pierre Torres, and Spanish journalists Marc Marginedas, Javier Espinosa, and Ricardo García Vilanova. The unit continues to hold hostage British journalist John Cantlie
and a female aid worker.[536]

Cyber-security group the
Citizen Lab
released a report finding a possible link between ISIL and a digital attack on the Syrian citizen media group Raqqa Is Being Slaughtered Silently
(RSS). Supporters of the media group received an emailed link to an image of supposed airstrikes, but clicking on the link introduced malware to the user's computer that sends details of the user's IP address and system each time it restarts. That information has been enough to allow ISIL to locate RSS supporters. "The group has been targeted for kidnappings, house raids, and at least one alleged targeted killing. At the time of that writing, ISIL was allegedly holding several citizen journalists in Raqqa", according to the Citizen Lab report.[537]

On 8 January 2015, ISIL members in Libya claimed to have executed Tunisian journalists Sofiene Chourabi and Nadhir Ktari who disappeared in September 2014.[538]
Also in January 2015, Japanese journalist Kenji Goto
was kidnapped and beheaded, after a demand for a $200 million ransom payment was not met.[539]

Beheadings and mass executions

An unknown number of Syrians and Iraqis, several Lebanese soldiers, male and female
Kurdish
fighters near Kobanî, two American journalists, one American and two British aid workers, 30 Ethiopian Christians[540]
and 21 Egyptian Coptic Christians
in Libya[541]
have been beheaded
by the Islamic State of Iraq and the Levant. ISIL uses beheadings to intimidate local populations and has released a series of propaganda videos aimed at Western countries.[50]
ISIL was reported to have beheaded about 100 foreign fighters as deserters who tried to leave Al-Raqqah.[542]

They also engage in public and mass executions of Syrian and Iraqi soldiers and civilians,[361]
sometimes forcing prisoners to dig their own graves before shooting lines of prisoners and pushing them in.[543][544]
Among the known mass executions of captured soldiers carried out by ISIL are those in Tikrit (ISIS executed
up to 1,700 Shia Iraqi Air Force
cadets from Camp Speicher
near Tikrit
on 12 June 2014),[545][546]Al-Thawrah
(ISIS executed 250 Syrian soldiers captured at the Al-Tabqa air base
between 27 and 28 August 2014),[547]Palmyra
(up to 280 Syrian soldiers and government loyalists were shot in the head or beheaded in a public square on 22 May 2015),[548]
and Deir ez-Zor
(ISIS killed at least 300 Syrian soldiers, pro-government militiamen and their families on 16 January 2016).[549]

ISIS executed 600 Shia prisoners in
Mosul
in June 2014.[550]
In November 2014, there were reports that ISIS fighters massacred more than 630 members of the Albu Nimr
tribe in Iraq. Albu Nimr was one of the Sunni Arab
tribes that fiercely opposed the Islamic State.[551]
On 17 December 2014, it was reported by Turkish media, that the ISIS had executed at least 150 women from the Albu Nimr tribe in Falluja
for refusing to marry ISIS militants.[552]

Use of chemical weapons

Kurds in northern Iraq reported being attacked by ISIS with chemical weapons in August 2015,[553]
which was later confirmed to be mustard gas.[554]
At Kobanî, it is highly likely that ISIS used chlorine
gas. These chemical weapons may be from a chemical weapons storage site at Al-Muthanna, which contained 2,500 chemical rockets. Although the rockets' chemical contents were deteriorated, ISIS may have used them in a concentrated manner.[555]

Destruction of cultural and religious heritage

UNESCO's Director-General
Irina Bokova
has warned that ISIL is destroying Iraq's cultural heritage, in what she has called "cultural cleansing". "We don't have time to lose because extremists are trying to erase the identity, because they know that if there is no identity, there is no memory, there is no history", she said. Referring to the ancient cultures of Christians, Yazidis and other minorities, she said, "This is a way to destroy identity. You deprive them of their culture, you deprive them of their history, their heritage, and that is why it goes hand in hand with genocide. Along with the physical persecution they want to eliminate – to delete – the memory of these different cultures. ... we think this is appalling, and this is not acceptable."[556]Saad Eskander, head of Iraq's National Archives said, "For the first time you have cultural cleansing... For the Yazidis, religion is oral, nothing is written. By destroying their places of worship ... you are killing cultural memory. It is the same with the Christians – it really is a threat beyond belief."[557]

The mosque dedicated to Jonah
in Mosul prior to its July 2014 demolition by ISIL

To finance its activities, ISIL is stealing artefacts from Syria[558]
and Iraq and sending them to Europe to be sold. UNESCO has asked for United Nations Security Council
controls on the sale of antiquities, similar to those imposed after the 2003 Iraq War. UNESCO is working with
Interpol, national customs authorities, museums, and major auction houses in attempts to prevent looted items from being sold.[557]
ISIL occupied Mosul Museum, the second most important museum in Iraq, as it was about to reopen after years of rebuilding following the Iraq War, saying that the statues were against Islam and threatening to destroy the museum's contents.[559][560]

ISIL considers worshipping at graves tantamount to
idolatry, and seeks to purify the community of unbelievers. It has used bulldozers to crush buildings and archaeological sites.[560]Bernard Haykel
has described al-Baghdadi's creed as "a kind of untamed Wahhabism", saying, "For Al Qaeda, violence is a means to an ends; for ISIS, it is an end in itself".[13]
The destruction by ISIL in July 2014 of the tomb and shrine of the prophet Yunus
– Jonah
in Christianity – the 13th-century mosque of Imam Yahya Abu al-Qassimin, the 14th-century shrine of prophet Jerjis –
St George
to Christians – and the attempted destruction of the Hadba
minaret at the 12th-century Great Mosque of Al-Nuri
have been described as "an unchecked outburst of extreme Wahhabism".[561]
"There were explosions that destroyed buildings dating back to the Assyrian
era", said National Museum of Iraq
director Qais Rashid, referring to the destruction of the shrine of Yunus. He cited another case where "Daesh (ISIL) gathered over 1,500 manuscripts from convents and other holy places and burnt all of them in the middle of the city square".[562]
In March 2015, ISIL reportedly bulldozed the 13th-century BC Assyrian city of Nimrud, believing its sculptures to be idolatrous.
UNESCO
head, Irina Bokova, deemed this to be a war crime.[563]

ISIL has burned or stolen collections of books and papers from the various locations including the
Central Library of Mosul
(which they rigged with explosives and burned down),[564]
the library at the University of Mosul, a Sunni Muslim library, a 265-year-old Latin Church and Monastery of the Dominican Fathers, and the Mosul Museum Library. Some destroyed or stolen works date back to 5000 BCE and include "Iraq newspapers dating to the early 20th century, maps and books from the Ottoman Empire, and book collections contributed by about 100 of Mosul's establishment families." The stated goal is to destroy all non-Islamic books.[565]

Many world leaders and government spokespeople have called ISIL a terrorist group or banned it, without their countries having formally designated it as such. The following are examples:

The Government of Germany banned ISIL in September 2014. Activities banned include donations to the group, recruiting fighters, holding ISIL meetings and distributing its propaganda,
flying ISIL flags,[590]
wearing ISIL symbols and all ISIL activities. "The terror organisation Islamic State is a threat to public safety in Germany as well", said German politician Thomas de Maizière. He added, "Today's ban is directed solely against terrorists who abuse religion for their criminal goals."[591]
Being a member of ISIL is also illegal in accordance with § 129a and § 129b of the German criminal code.[592]

In October 2014, Switzerland banned ISIL's activities in the country, including propaganda and financial support of the fighters, with prison sentences as potential penalties.[593]

In mid-December 2014, India banned ISIL after the arrest of an operator of a pro-ISIL Twitter account.[594]

Pakistan designated ISIL as a banned organisation in late August 2015, under which all elements expressing sympathy for the group would be blacklisted and sanctioned.[588]

Terrorist group, militia, or territorial authority

By 2014, ISIL was increasingly being viewed as a
militia
rather than just a terrorist group.[596]
As major Iraqi cities fell to ISIL in June 2014, Jessica Lewis, a former US Army intelligence officer at the Institute for the Study of War, described ISIL at that time as

not a terrorism problem anymore, [but rather] an army on the move in Iraq and Syria, and they are taking terrain. They have shadow governments in and around
Baghdad, and they have an aspirational goal to govern. I don't know whether they want to control Baghdad, or if they want to destroy the functions of the Iraqi state, but either way the outcome will be disastrous for Iraq.[596]

an advanced military leadership. They have incredible command and control and they have a sophisticated reporting mechanism from the field that can relay tactics and directives up and down the line. They are well-financed, and they have big sources of manpower, not just the foreign fighters, but also prisoner escapees.[596]

Former US Defense Secretary
Chuck Hagel
saw an "imminent threat to every interest we have", but former top counter-terrorism adviser Daniel Benjamin
derided such talk as a "farce" that panics the public.[597]

In actuality, Isis is the canniest of all traders in the flourishing international economy of disaffection: the most resourceful among all those who offer the security of collective identity to isolated and fearful individuals. It promises, along with others who retail racial, national and religious supremacy, to release the anxiety and frustrations of the private life into the violence of the global.[599]

Criticism

Islamic criticism

Around the world,
Islamic religious leaders
have overwhelmingly condemned ISIL's ideology and actions, arguing that the group has strayed from the path of true Islam and that its actions do not reflect the religion's real teachings or virtues.[600]

Extremism within Islam goes back to the 7th century, to the
Khawarijes. From their essentially political position, the Kharijites developed extreme doctrines which set them apart from both mainstream Sunni and Shia Muslims. They were particularly noted for adopting a radical approach to
takfir, whereby they declared other Muslims to be unbelievers and therefore deemed worthy of death.[601][602][603][604]
Other scholars have also described the group not as Sunnis, but as Khawarij.[602][605]
Sunni critics, including Salafi
and jihadist muftis
such as Adnan al-Aroor
and Abu Basir al-Tartusi, say that ISIL and related terrorist groups are not Sunnis, but are instead modern-day Kharijites (Muslims who have stepped outside the mainstream of Islam) serving an imperial anti-Islamic agenda.[606]

ISIL has received severe criticism from Muslim religious scholars and theologians. In late August 2014, the
Grand Mufti
of Saudi Arabia, Abdul-Aziz ibn Abdullah Al ash-Sheikh, condemned ISIL and
al-Qaeda
saying, "Extremist and militant ideas and terrorism which spread decay on Earth, destroying human civilization, are not in any way part of Islam, but are enemy number one of Islam, and Muslims are their first victims".[607]
In late September 2014, 126 Sunni imams
and Islamic scholars—primarily Sufi[608]—from around the Muslim world signed an
open letter
to the Islamic State's leader al-Baghdadi, explicitly rejecting and refuting his group's interpretations of Islamic scriptures, the Quran
and hadith, which it used in order to justify its actions.[525][609]
"[You] have misinterpreted Islam into a religion of harshness, brutality, torture and murder ... this is a great wrong and an offence to Islam, to Muslims and to the entire world", the letter states.[524]
It rebukes the Islamic State for its killing of prisoners, describing the killings as "heinous war crimes" and its persecution of the
Yazidis
of Iraq as "abominable". Referring to the "self-described 'Islamic State'", the letter censures the group for carrying out killings and acts of brutality under the guise of jihad—holy struggle—saying that its "sacrifice" without legitimate cause, goals and intention "is not jihad at all, but rather, warmongering and criminality".[524][610]
It also accuses the group of instigating fitna—sedition—by instituting slavery under its rule in contravention of the
anti-slavery consensus
of the Islamic scholarly community.[524]

Kurdish demonstration against ISIL in Vienna, Austria, 10 October 2014

According to
The New York Times, "All of the most influential jihadist theorists are criticising the Islamic State as deviant, calling its self-proclaimed caliphate null and void" and they have denounced it for its beheadings of journalists and aid workers.[13]
ISIL is widely denounced by a broad range of Islamic clerics, including al-Qaeda-oriented clerics and Saudi clerics.[12][13]Muhammad al-Yaqoubi
states, "It is enough of a proof of the extreme ideology of ISIS that the top leaders of Salafi-Jihadism have disclaimed it."[611]
Other critics of ISIL's brand of Sunni Islam include Salafists who previously publicly supported jihadist groups such as al-Qaeda: for example, the Saudi government official Saleh Al-Fawzan, known for his extremist views, who claims that ISIL is a creation of "Zionists, Crusaders and Safavids", and the Jordanian-Palestinian writer
Abu Muhammad al-Maqdisi, the former spiritual mentor to
Abu Musab al-Zarqawi, who was released from prison in Jordan in June 2014 and accused ISIL of driving a wedge between Muslims.[606]

The group's declaration of a caliphate has been criticised and its legitimacy has been disputed by Middle Eastern governments, other jihadist groups,[612]
and by Sunni Muslim
theologians and historians. Qatar-based TV broadcaster and theologian Yusuf al-Qaradawi
stated: "[The] declaration issued by the Islamic State is void under sharia
and has dangerous consequences for the Sunnis in Iraq and for the revolt in Syria", adding that the title of caliph can "only be given by the entire Muslim nation", not by a single group.[613]
The group's execution of Muslims for breach of traditional sharia
law while violating it itself (encouraging women to emigrate to its territory, travelling without a Wali—male guardian—and in violation of his wishes) has been criticised;[614]
as has its love of archaic imagery (horsemen and swords) while engaging in bid‘ah
(religious innovation) in establishing female religious police (known as Al-Khansaa Brigade).[615]
In a similar vein, the Syrian Islamic scholarMuhammad al-Yaqoubi
says, "[t]he followers of ISIS do not want to adhere to Islamic law but rather they want to twist Islamic law to conform to their fantasies. To this end, they pick and choose the evidences that corroborate their misguidance, despite being weak or abrogated."[616]

Two days after the beheading of
Hervé Gourdel, hundreds of Muslims gathered in the
Grand Mosque of Paris
to show solidarity against the beheading. The protest was led by the leader of the French Council of the Muslim Faith,
Dalil Boubakeur, and was joined by thousands of other Muslims around the country under the slogan "Not in my name".[617][618]
French president François Hollande
said Gourdel's beheading was "cowardly" and "cruel", and confirmed that airstrikes would continue against ISIL in Iraq. Hollande also called for three days of national mourning, with flags flown at half-mast throughout the country and said that security would be increased throughout Paris.[617]

An
Islamic Frontsharia
court judge in Aleppo, Mohamed Najeeb Bannan, stated: "The legal reference is the Islamic Sharia. The cases are different, from robberies to drug use, to moral crimes. It's our duty to look at any crime that comes to us. . . After the regime has fallen, we believe that the Muslim majority in Syria will ask for an Islamic state. Of course, it's very important to point out that some say the Islamic Sharia will cut off people's hands and heads, but it only applies to criminals. And to start off by killing, crucifying etc. That is not correct at all." In response to being asked what the difference between the Islamic Front's and ISIL's version of sharia would be, he said, "One of their mistakes is before the regime has fallen, and before they've established what in Sharia is called Tamkeen [having a stable state], they started applying Sharia, thinking God gave them permission to control the land and establish a Caliphate. This goes against the beliefs of religious scholars around the world. This is what [IS] did wrong. This is going to cause a lot of trouble. Anyone who opposes [IS] will be considered against Sharia and will be severely punished."[619][620]

Al-Qaeda and al-Nusra have been trying to take advantage of ISIL's rise, by attempting to present themselves as "moderate" compared to "extremist" ISIL, although it has the same aim of establishing sharia and a caliphate but doing so in a more gradual manner.[621][622][623][624][625]
Al-Nusra has criticised the way in which ISIL fully and immediately institutes sharia in the areas that fall under its control, since it alienates people too much. It supports the gradual, slower approach favoured by al-Qaeda, preparing society to accept sharia and indoctrinating people through education before implementing the hudud
aspects of sharia, such as throwing gays from the top of buildings, chopping limbs off, and public stoning.[159]
Al-Nusra and ISIL are both hostile towards the Druze. However, while al-Nusra has typically destroyed Druze shrines and pressured them to convert to Sunni Islam, ISIL regards the entire Druze community as a valid target for violence, as it does the
Yazidis.[626]

Ayman al-Zawahiri, the leader of al-Qaeda, has called for consultation (shura) within the "prophetic method" to be used when establishing the caliphate, criticising al-Baghdadi for not following the required steps. Al-Zawahiri has called upon ISIL members to close ranks and join al-Qaeda in fighting against Assad, the
Shia, Russia, Europe, and America and to stop the infighting between jihadist groups. He called upon jihadists to establish Islamic entities in Egypt and the Levant, slowly implementing sharia before establishing a caliphate, and has called for violent assaults against America and the West.[627]

Great Pyramid
of Giza lit up by images of the flags of France, Lebanon and Russia in solidarity with victims of recent terrorist attacks, 16 November 2015

The
Jaysh al-Islam
group within the Islamic Front
criticised ISIL, saying: "They killed the people of Islam and leave the idol worshippers ... They use the verses talking about the disbelievers and implement it on the Muslims".[628]
The main criticism of defectors from ISIL has been that the group is fighting and killing other Sunni Muslims,[629]
as opposed to just non-Sunnis being brutalised.[630][631]
In one case, a supposed defector from ISIL executed two activists of a Syrian opposition group in Turkey who had sheltered them.[632]

The current
Grand Imam of al-Azhar
and former president of al-Azhar University,
Ahmed el-Tayeb, has strongly condemned the Islamic State, stating that it is acting "under the guise of this holy religion and have given themselves the name 'Islamic State' in an attempt to export their false Islam".[633][634]
Citing the Quran, he stated: "The punishment for those who wage war against God and his Prophet and who strive to sow corruption on earth is death, crucifixion, the severing of hands and feet on opposite sides or banishment from the land. This is the disgrace for them in this world and in the hereafter they will receive grievous torment." Although el-Tayeb has been criticised for not expressly stating that the Islamic State is heretical,[635][636]
the Ash'ari
school of Islamic theology, to which el-Tayeb belongs, does not allow calling a person who follows the
shahada
an apostate.[635]
El-Tayeb has strongly come out against the practice of takfirism
(declaring a Muslim an apostate) which is used by the Islamic State to "judge and accuse anyone who doesn’t tow their line with apostasy and outside the realm of the faith" declaring "Jihad
on peaceful Muslims" using "flawed interpretations of some Qur’anic texts, the prophet's Sunna, and the Imams’ views believing incorrectly, that they are leaders of Muslim armies fighting infidel peoples, in unbelieving lands".[637]

In late December 2015, nearly 70,000 Indian Muslim clerics associated with the Indian
Barelvi
movement issued a fatwa
condemning ISIL and similar organisations, saying they are "not Islamic organisations". Approximately 1.5 million Sunni Muslim followers of this movement have formally decried violent extremists.[638][639][640]

Whether Sunni or Shia, Salafi or Sufi, conservative or liberal, Muslims – and Muslim leaders – have almost unanimously condemned and denounced ISIL not merely as un-Islamic but actively anti-Islamic.[641]

that because the Islamic State "bases its teachings on religious texts that mainstream Muslim clerics do not want to deal with head on, new recruits leave the camp feeling that they have stumbled on the true message of Islam".[145]
In mid-February 2015, Graeme Wood, a lecturer in political science at Yale University, said in
The Atlantic, "The religion preached by its most ardent followers derives from coherent and even learned interpretations of Islam."[153]

Yusuf al-Qaradawi, an Egyptian
Islamic theologian
based in Qatar, said in his official website that the "United Arab Emirates (UAE) and the leaders of Daesh (ISIS/ISIL) terrorist group are from one species and they are two sides of the same coin".[642]

International criticism

The group has attracted widespread criticism internationally for its extremism, from governments and international bodies such as the
United Nations
and Amnesty International. On 24 September 2014,
United Nations Secretary-GeneralBan Ki-Moon
stated: "As Muslim leaders around the world have said, groups like ISIL – or Da’ish – have nothing to do with Islam, and they certainly do not represent a state. They should more fittingly be called the 'Un-Islamic Non-State'."[643]
ISIL has been designated a terrorist organisation
by the United Nations, the European Union and its member states, the United States, Russia, India, Indonesia, Israel, Turkey, Saudi Arabia, Syria, Iran and other countries. Over 60 countries are directly or indirectly waging war against ISIL. The group was described as a
cult
in a Huffington Post
column by notable cult authority Steven Hassan.[644]

The name "Islamic State" and "caliphate" declaration

The group's declaration of a new caliphate in June 2014 and its adoption of the name "Islamic State" have been criticised and ridiculed by Muslim scholars and rival Islamists both inside and outside the territory it controls.[247][248][249][645]
In a speech in September 2014, President Obama said that ISIL is not "Islamic" on the basis that no religion condones the killing of innocents and that no government recognises
the group as a state,[253]
while many object to using the name "Islamic State" owing to the far-reaching religious and political claims to authority which that name implies. The United Nations Security Council,[250]
the United States,[253]
Canada,[251]
Turkey,[646]
Australia,[252]
Russia,[647]
the United Kingdom[648]
and other countries generally call the group "ISIL", while much of the Arab world uses the Arabic
acronym "Dāʻish". France's Foreign Minister Laurent Fabius said "This is a terrorist group and not a state. I do not recommend using the term Islamic State because it blurs the lines between Islam, Muslims, and Islamists. The Arabs call it 'Daesh' and I will be calling them the 'Daesh cutthroats.'"[649]
Retired general John Allen, the US envoy appointed to co-ordinate the coalition, US military Lieutenant General James Terry, head of operations against the group, and Secretary of State John Kerry had all shifted towards use of the term DAESH by December 2014.[650]

In late August 2014, a leading Islamic educational institution,
Dar al-Ifta al-Misriyyah
in Egypt, advised Muslims to stop calling the group "Islamic State" and instead refer to it as "Al-Qaeda Separatists in Iraq and Syria" or "QSIS", because of the militant group's "un-Islamic character".[651][652]
When addressing the United Nations Security Council in September 2014, Australian Prime Minister Tony Abbott
summarised the widespread objections to the name "Islamic State" thus: "To use this term [Islamic State] is to dignify a death cult; a death cult that, in declaring itself a caliphate, has declared war on the world".[653]
The group is very sensitive about its name. "They will cut your tongue out even if you call them ISIS – you have to say 'Islamic State'", said a woman in ISIL-controlled Mosul.[654]

In mid-October 2014, representatives of the
Islamic Society of Britain, the
Association of British Muslims
and the UK's Association of Muslim Lawyers
proposed that "'Un-Islamic State' (UIS) could be an accurate and fair alternative name to describe this group and its agenda", further stating, "We need to work together and make sure that these fanatics don't get the propaganda that they feed off."[655][656]
The "Islamic State" is mocked on social media websites such as Twitter and YouTube, with the use of hashtags, mock recruiting ads, fake news articles and YouTube videos.[657]

Countries and groups at war with ISIL

ISIL's claims to territory have brought it into armed conflict with many governments, militias and other armed groups. International rejection of ISIL as a terrorist entity and rejection of its claim to even exist have placed it in conflict with countries around the world.

The Global Coalition to Counter the Islamic State of Iraq and the Levant

The Global Coalition to Counter the Islamic State of Iraq and the Levant (ISIL), also referred to as the Counter-ISIL Coalition or Counter-DAESH Coalition,[703]
is a US-led group of nations and non-state actors
that have committed to "work together under a common, multifaceted, and long-term strategy to degrade and defeat ISIL/Daesh". According to a joint statement issued by 59 national governments and the European Union on 3 December 2014, participants in the Counter-ISIL Coalition are focused on multiple lines of effort:[704]

The following multi-national organisations are part of the Counter-ISIL Coalition:[704]
Arab League — coordinating member response[705]
European Union – declared to be part, 27 members are participating, Malta not participating;[704]
